By running: systemctl status snap.docker.dockerd.service I was able to see which was the loaded service file: /etc/systemd/system/snap.docker.dockerd.service Just looked inside this file looking for the ExecStart directive. It was there. So just had to add -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock to that line, so it ended up looking like: ExecStart=/usr/bin/snap run docker.dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock Rebooted. Works.
